Adaptive Radiation of the Hawaiian Silversword Alliance

Hybridization

Last Modification: February 3, 2003

The crossing diagram at the left shows hybrid combinations that are known to occur in
nature or that have been artificially created. Argyro=Argyroxiphium, Dubaut=Dubautia,
Wilkes=Wilkesia. As may readily be seen, hybrids have been produced between some
of the most divergent members of the silversword alliance. The results suggest that any
two members of this alliance may be expected to have the potential to produce viable
hybrid progeny.
